Advanced Electric-To-Acoustic Guitar Modeling

How many times have you been onstage or in the studio with your electric guitar, and wished that you’d brought an acoustic along? For musicians who travel light, hauling an extra guitar to the gig isn’t always the most attractive option. BOSS AC-3 to the rescue! This new-generation compact pedal employs COSM® modeling technology to transform any electric guitar into a variety of beautiful acoustic guitars.

  • - BOSS’s most advanced acoustic-guitar modeling in a compact pedal
  • - Four simulation modes: Standard, Jumbo, Enhanced, and Piezo-equipped
  • - Top and Body knobs for fine-tuning the virtual-body resonance
  • - Built-in reverb, optimized for acoustic-guitar simulation

Advanced Modeling

BOSS’s COSM Acoustic-Modeling technology is beautifully showcased in this small but powerful pedal, which simulates an acoustic guitar much more precisely and realistically than previous technology allowed. Derived from BOSS top-of-the-line AD-8, the AC-3 simulates the sound of an acoustic guitar with incredible precision. Four simulation modes are provided: Standard, Jumbo, Enhanced, and Piezo-equipped; the latter supplies that famous “cut through the mix” direct piezo sound. Previous compact acoustic-guitar modeling-pedals were promising, but now the bar has been raised with AC-3.

Fine Control

Top and Body controls are provided, which allow you to shape the characteristics of the four acoustic models. Create the perfect acoustic-guitar sound quickly and easily with simple knob twists.

Reverb Included

Add depth and sweetness to the sound with the AC-3’s built in digital reverb. It’s like getting two pedals in one!
